State health officials have extended to the Sonoma Coast recent warnings about the risks of consuming sport-caught mussels, clams, oysters, whole scallops and other bivalves in the wake of testing that has turned up evidence of naturally occurring paralytic shellfish poisoning in recent weeks.
The expanded notice comes as Marin County Public Health announced its first confirmed case of human illness, which occurred in a patient who ate mussels harvested Sunday at Dillon Beach, officials said Wednesday.
The unidentified patient had been hospitalized for neurological symptoms and is “getting better,” Marin County Public Health Director Matthew Willis said in a news release. “Fortunately, the clinician was aware of the elevated PSP (paralytic shellfish poisoning) levels in locally sport-harvested shellfish and made a timely diagnosis,” he said.
State health officials last week issued notices about the dangers of eating recreationally caught shellfish off the coast of San Mateo, San Francisco and Marin counties because of unhealthy levels of harmful toxins produced in phytoplankton blooms that tend to thrive in springtime conditions off the Northern California coast.
